Title:
IMAGING SYSTEM, PHOTOGRAPHING MODULE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/205217
Kind Code:
A1
Abstract:
The present application discloses an imaging system, a photographing module, and an electronic device. The imaging system comprises in sequence along the optical axis from an object side to an image side a first lens having a positive focal power, a second lens having a negative focal power, a third lens having a focal power, a fourth lens having a focal power, a fifth lens having a positive focal power, and a sixth lens having a negative focal power. The surface shapes of the six lenses are reasonably matched, thus allowing the imaging system to also satisfy the conditional expression of: 1.5 mm < Imgh2/TTL/Fno < 1.9 mm, where Imgh is half of the image height corresponding to the maximum field-of-view angle of the imaging system, TTL is the distance on the optical axis from the object-side surface of the first lens of the imaging system to an imaging surface of the imaging system, and Fno is the number of apertures of the imaging system. Meeting the design described above, implemented for the imaging system are a miniaturized design, a large field-of-view feature, and increased imaging clarity.
